Remove BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENT

Browse Source 
This makes boost::config independent of boost::core in the
modularized repos.

(from Stephen Kelly)

Daniel James: The original patch included changes for several libraries.
I'll deal with them later, they shouldn't break since the changes were to
remove code that won't be activated any more.

The compiler does not perform function template ordering or its function
template ordering is incorrect.

// BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//
//
// Some compilers have problems with function templates whose template
// parameters don't appear in the function parameter list (basically
// they just link one instantiation of the template in the final
// executable). These macros provide a uniform way to cope with the
// problem with no effects on the calling syntax.
// Example:
//
// #include <iostream>
// #include <ostream>
// #include <typeinfo>
//
// template <int n>
// void f() { std::cout << n << ' '; }
//
// template <typename T>
// void g() { std::cout << typeid(T).name() << ' '; }
//
// int main() {
// f<1>();
// f<2>();
//
// g<int>();
// g<double>();
// }
//
// With VC++ 6.0 the output is:
//
// 2 2 double double
//
// To fix it, write
//
// template <int n>
// void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }
//
// template <typename T>
// void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
